How To Add A New Load-Sharing Mirror on NetApp Cluster Mode using PowerShell

To protect the Storage Virtual Machine (SVM) namespace root volume, you can create a load-sharing mirror volume on every node in the cluster, including the node in which the root volume is located. Then you create a mirror relationship to each load-sharing mirror volume and initialize the set of load-sharing mirror volumes. As you add new nodes to the cluster, you may choose to add a new load-sharing mirror to a set of existing load-sharing mirrors.

Create the destination load-sharing mirror volume by using the New-NcVol cmdlet with the -type parameter set to DP (data-protection volume). The destination volume that you create must be the same size or greater than the SVM root volume.

Use the Invoke-NcSnapmirrorInitialize cmdlet specifying the DestinationVolume and DestinationVserver to perform the initial update of a SnapMirror relationship.

Note: Do not use the Invoke-NcSnapmirrorLsInitialize cmdlet. The Invoke-NcSnapmirrorLsInitialize cmdlet is for initializing volumes for an entire set of load-sharing mirrors, not for initializing an individual volume.

Upon job completion, update the LS set by using the Invoke-NcSnapmirrorLsUpdate cmdlet specifying the source endpoint to update destination volumes of the set of load-sharing mirrors. The cmdlet makes destination volumes in the group of load-sharing mirrors up-to-date mirrors of the source volume. Separate SnapMirror transfers are performed from the source volume to each of the up-to-date destination volumes in the set of load-sharing mirrors.

Use the Get-NcSnapmirror cmdlet once more to confirm the health of the relationship.
